Loading health status...
Converts an image URL or JPEG Base64 input into an image reference for a selected 1688 image search endpoint. Use it to prepare external images for visual product sourcing.
Highlights
Guidance
Supply exactly one of url and imgBase64. Base64 input must be JPEG and no larger than 100 KB. Pass the returned image reference unchanged to the selected image search endpoint.
Parameters
| Name | In | Type | Required | Default | Description |
|---|---|---|---|---|---|
token | query | string | Yes | - | Access token for this API service. |
Request Body
json
{
"url": "string",
"imgBase64": "string",
"searchApiEndpoint": "standard"
}Code Samples
bash
curl --max-time 120 -X POST 'https://api.justoneapi.com/api/1688/convert-image/v1?token=YOUR_API_KEY' \
-H 'Content-Type: application/json' \
-d '{"url":"string","imgBase64":"string","searchApiEndpoint":"standard"}'text
I want to use the "Image Conversion (V1)" API from Just One API.
Base URL: https://api.justoneapi.com.
API Path: /api/1688/convert-image/v1?token=YOUR_API_KEY
API Endpoint: BASE_URL + /api/1688/convert-image/v1?token=YOUR_API_KEY
HTTP Method: POST
Authentication: Append the "token" query parameter to the URL.
OpenAPI Definition: https://docs.justoneapi.com/openapi/1688/image-conversion-v1-en.json
Request headers:
- Content-Type: application/json
Parameters:
- token (query): Access token for this API service. (Required)
Request Body (JSON):
{
"url": "string",
"imgBase64": "string",
"searchApiEndpoint": "standard"
}
Return format: safely handle JSON or text according to the actual Content-Type.
Response Handling & Error Codes:
1. Business results should be determined by the "code" field in the response body (code 0 means success).
2. Timeout Recommendation: Set the request timeout to 120 seconds. If 120 seconds is too long for your use case, use at least 60 seconds, but a small number of requests may time out before receiving a result.
3. Business Code Reference:
- 0: Success
- 100: Invalid or Inactive Token
- 301: Collection Failed. Please Retry.
- 302: Rate Limit Exceeded
- 303: Daily Quota Exceeded
- 400: Invalid Parameters
- 500: Internal Server Error
- 600: Permission Denied
- 601: Insufficient Balance
- 602: Token Budget Exceeded
4. Code 601 means the shared account balance is insufficient. Code 602 means the current API token's own cumulative budget limit has been reached. Token budget limits do not transfer funds out of the shared account balance.
Please help me write a script in my preferred programming language to call this API and handle the response.python
